Pricing
EnterpriseSwimm does not publish list prices. Engagements are scoped by the size of the codebase, measured in lines of code, and delivered in fixed-price stages rather than per-seat subscriptions. Buyers typically start with an Assessment or a proof of concept to validate the approach on their own code, then move to Specification, Modernization and Enablement stages as scope is agreed. Contact the sales team (info@swimm.io) for a quote. There is no self-serve plan or free tier currently advertised, so earlier per-seat figures seen on third-party sites may be outdated. Confirm current terms with Swimm directly.
FreeCline itself is free and open source — there are no seat fees or subscriptions for the core agent. You pay AI inference costs directly to your chosen LLM provider (Anthropic, OpenAI, Google, etc.) with a full per-request cost breakdown shown in the UI. Cline shows every token used and every dollar spent transparently. ClinePass ($9.99/month) is an optional managed billing subscription that provides 2–5x more usage on popular open coding models compared to standard API rates, with one-click sign-in and no need to manage API keys yourself. It is not required — BYOK (bring your own key) is always available at zero markup. Enterprise pricing is custom and adds JetBrains extension, SSO/OIDC/SCIM, SLA, centralized billing, RBAC, team management dashboard, authentication logs, limit inference providers, dedicated support, VPC deployments, OpenTelemetry, and advanced config management.

Open-source AI coding agent — any model, your keys, full control
Swimm

Swimm Pros & Cons

Pros

  • Purpose-built for hard legacy and mainframe modernization problems
  • Fixed-price staged delivery makes large projects easier to budget
  • On-prem and air-gapped options suit regulated industries
  • Context layer can feed other AI agents through MCP
  • Strong security certifications for enterprise procurement

Cons

  • No public pricing or self-serve free tier
  • Overkill for small teams that only need internal docs
  • Heavier engagement model than an IDE plugin or wiki
  • Messaging has shifted from documentation to modernization, which may confuse earlier users
Cline

Cline Pros & Cons

Pros

  • Completely free and open source (Apache 2.0) — no seat fees, no subscriptions, no proprietary lock-in ever
  • 67K+ GitHub stars and 8M+ developers — largest open-source coding agent community by any measure
  • Full cost transparency at zero markup — the only major coding agent that shows exactly what you pay per request with no hidden pricing
  • Model-agnostic with 12+ provider integrations — switch any time without changing workflow or losing your setup
  • Plan/Act mode gives full human-in-the-loop control — approve every action or flip to autopilot when confidence is high
  • Trusted by engineers at Salesforce, Oracle, Amazon, Microsoft, eBay, Visa, IBM, and LG

Cons

  • BYOK means you manage your own LLM API keys and billing — can be confusing for non-technical users used to flat subscriptions
  • No built-in inline autocomplete (Tab completions) — Cline is an agent, not a code-completion tool like Copilot or Tabnine
  • JetBrains support is still Early Access — not as polished as the VS Code extension
  • Some engineers joining OpenAI's Codex team in January 2026 raised community concerns about long-term momentum (Cline confirmed no acquisition and remains independent)
  • Enterprise features (SSO, RBAC, JetBrains, SLA) require a custom sales contract — no self-serve team plan available
